"Many of these batteries are internal to the system, which means they are not customer replaceable," the Palo Alto-based technology company said. "HP is providing battery replacement services by an authorized technician at no cost. HP is also providing a BIOS update that places the battery in 'Battery Safety Mode' so that the notebook or workstation can be safely used without the battery by connecting to an HP power adapter."

HP has been informed of eight incidents of batteries overheating, charring or melting, including three reports of property damage totaling $4,500. One user suffered a minor burn injury to the hand.

The products were sold at Best Buy and authorized dealers nationwide, as well as online at www.Amazon.com, www.hp.com and other websites.

The batteries were shipped in Notebook computers and Mobile Workstations available from December 2015 through December 2017 for between $300 and $4,000. They were sold invididually for between $50 and $90.
